Thats one of the several reasons I belive the path should be to
have the dos verify_checksum program read the checksum.sum and
work from it! This would side step alot of dos's brain deadness!
The only maintiance would be if the output of FreeBSD's cksum
changed. Not likly.
fhandle = fopen("checksum.sum", ...)
while(fgets(buf, len, fhandle) != EOF) {
parse(buf);
crc = do_crc(findfile(buf_filename));
if (crc == valid_crc)
it's ok
else
it's broke download it again!
}
-Enjoy
